NOTE: this might be the same vulnerability as CVE-2013-2053 and CVE-2013-2054. | |||||
| CVE-2012-2388 | 1 Strongswan | 1 Strongswan | 2025-04-11 | 7.5 HIGH | N/A |
| The GMP Plugin in strongSwan 4.2.0 through 4.6.3 allows remote attackers to bypass authentication via a (1) empty or (2) zeroed RSA signature, aka "RSA signature verification vulnerability." | |||||
